[Kernel-packages] [Bug 1731968] Re: 384.90-0ubuntu0.16.04.2 EGL crashes at startup
I've been documenting my attempt to work around this problem here: https://stackoverflow.com/questions/47415198/missing-gl-version-from- glewinit-using-egl/54668271#54668271 I discovered an nvidia blog post - https://devblogs.nvidia.com/linking- opengl-server-side-rendering/ - which says: "If you want to use EGL context management instead, link against libOpenGL.so and libEGL.so." After installing the nvidia-410 package, as reported in the original post, the EGL test program from the original post doesn't work if linking against libGL.so: $ wget https://gist.githubusercontent.com/funchal/bff0a8d6dae5b3ace1a88c392416b5bc/raw/1427821a2390a30779881ab59c55b5550a468919/main.c $ gcc main.c -lGL -lEGL $ ./a.out egl 1.5 a.out: main.c:53: main: Assertion `renderer' failed. Aborted (core dumped) However it does work if linking against libOpenGL.so: $ wget https://gist.githubusercontent.com/funchal/bff0a8d6dae5b3ace1a88c392416b5bc/raw/1427821a2390a30779881ab59c55b5550a468919/main.c $ gcc main.c -L/usr/lib/nvidia-410 -lOpenGL -lEGL $ ./a.out egl 1.5 renderer: Tesla K80/PCIe/SSE2 version: 4.6.0 NVIDIA 410.78 With installing via a runfile as mentioned by mmatl in post #8, the test program works when linking against either libGL.so or libOpenGL.so. The difference between the packaged and runfile drivers may be due to the dependencies linked into libGL.so (I included a comparison in the stackoverflow post). The final solution is therefore to link against libOpenGL.so instead of libGL.so. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1731968 Title: 384.90-0ubuntu0.16.04.2 EGL crashes at startup Status in nvidia-graphics-drivers package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-384 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-390 package in Ubuntu: Confirmed Bug description: Release: Ubuntu 16.04.3 LTS Package version: 384.90-0ubuntu0.16.04.2 In the latest driver 384.90-0ubuntu0.16.04.2, EGL initialisation is now broken and the GL context returned is inconsistent leading to crashes.

This works when installing using the runfile method, but fails for the packaged drivers. So it definitely appears to be a packaging issue specific to Ubuntu. Confirmed to work on Fedora and Arch with 390-series drivers as well. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1731968 Title: 384.90-0ubuntu0.16.04.2 EGL crashes at startup Status in nvidia-graphics-drivers package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-384 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-390 package in Ubuntu: Confirmed Bug description: Release: Ubuntu 16.04.3 LTS Package version: 384.90-0ubuntu0.16.04.2 In the latest driver 384.90-0ubuntu0.16.04.2, EGL initialisation is now broken and the GL context returned is inconsistent leading to crashes.

This is still a problem in 396.45 on Ubuntu 16.04. The minimal test case fails, and EGL doesn't work cleanly.
